How much boost can d16y8 hold?

Well it depends...
Your Y8 probably wouldn't even hold 1lb of boost on say... Borg Warner s372r without blowing up (assuming it would even spool a turbo that big)
On the counter note, it could hold 35lbs of boost on a turbo the size of a pop can all day long.
You're asking a very common, yet retarded question. You need to know specifics on turbo size before you go asking how much boost will it hold.

just to give you an idea. i ran a t3/t4 on my stock d on 8 psi with a good tune. i personally didnt have the balls to push more than 8.
Because a turbo looks sooo cool under the hood of your car, who cares about performance?
hey man, you ask a stupid question and you get a stupid answer. This site is packed with info on turbo builds. If you come along and expect to be spoon fed by guys who have done their research and have the knowledge, then one can expect answers like this. Also, any forced induction question like this should be posted in the forced induction section of the forum.
Ive never heard anything like:
"i was thinking about just turbocharging my civic for the hell of it , i don't wanna push to much on my motor, just want it for looks and little performance" in my life. If you want a little performance, try a 50 shot.
People like us have bled,sweated,saved up, and researched for our power goals and our builds.
Now, with all that being said, do you understand where everyone is coming from when u post something like that?

Those opinions were given because you asked a dumb question. To ask how much boost a motor can hold is way to wide open. You can take a gt series turbo and put it on 8 lbs and it wont take long to blow your motor. But you take a small t25 on 8 lbs and you can run it all day long.
What you shoulda asked is how much whp can your single cam take because then people wouldnt of corrected you.
If you stick around here you'll learn to realize you ask dumb or over repeated questions your gonna get flamed for it. If you cant get that well then your time here will be short lived. Read up on your turbo info. Googles there for a reason
you beat me to it, pretty much said the same thing lol
This is still irrelevant, t3/t4 what? whats the trim, compressor (inlet), turbine (discharge)?
Heres more info and some math for you.
Calculate airflow for the X axis: measured in lb/min, airflow = (HP target) x (air/fuel ratio) x (BSFC/60) where BSFC is lbs fuel / (hp x hr) If you don't have access to BSFC data, you can plug in an estimated value between .50-.60.
Calculate volumetric efficiency = (actual CFM / theoretical CFM) x 100 where theoretical CFM = (RPM x CID) / 3456 and actual CFM = 90%, a good average number if you don't have access to measuring this. Multiply by .0610237 to convert cubic centimeter displacement into cubic inches.
Calculate manifold absolute pressure: map = [(airflow) x (639.6) x (460 + intake temperature)] / (VE) x (RPM/2) x (CID) Upwards of 100 degrees F is a good estimate for intercooled intake temps if you don't have access to measuring this. Plan on adding about 1psi to take into account pressure drops related to the intake and/or intercooler.
Calculate pressure ratio for the Y axis = (14.7 + map) / 14.7 If you're at sea level, 14.7psi will work. As elevation varies, this figure will need to be adjusted.
Note: Don't worry about the constants like 3456, 60 or 639.6, they're simply there to tidy things up and convert units.
VE = volumetric efficiency
BSFC = brake specific fuel consumption
HP = projected flywheel horsepower
CFM = cubic feet per minute
CID = cubic inch displacement
Other useful calculations:
Trim = (minor/major)squared x 100
Phantom tells the truth! See what research will do to you.. one day you can spit out info like Phantom here LOL
Whats the trim, compressor (inlet), turbine (discharge)?
ANOTHER useless post.
I'm not even a turbo guy and I've been doing alot of research on it lately because I'm kind of tired of reading all these posts.
